We have a couple of missing balusters/spindles. They're 'square turned'
IOW a square section, about 40mm square at the widest.

It hasn't really bothered us - I've been casually looking for years and
have an eBay alert set up, but to no avail. Now it's coming up to time
to sell the house and move on, I'd like to replace them. I had started
to think these were unique to us and our neighbours when I came across
this...

....which is an expired Isle-of-Wight-bay listing. They're identical,
and we're near Reading, so obviously not unique. Getting them made
would be expensive because of the square section and the two are
different - one is from a horizontal run along a landing and the other
is a shortened angled version from floor to underside of next flight.

Anyone seen these around or have other suggestions?

Cheers
